Abstract
En 中文
Highly stretchable and transparent ionic conducting materials enable electronic devices to have a distinguishable working mechanism and performances from the conventional electronics. Compared with hydrogels which contain large amounts of water to dissolve ions, ionic conductive elastomers (ICEs) are solvent-free, and intrinsically immune from dehydration. However, the current manufacturing technologies constrain the ICE-based ionotronics to simple and bulk geometries with single material, which greatly limits functionality and performance of ICEs-based ionotronics. Herein, a stretchable ultraviolet curable ICEs (SUV-ICEs) for 3D printing approach to fabricate complex 3D flexible electronics is reported. The developed SUV-ICEs are highly stretchable and thermally stable. Using a self-built DLP-based 3D printer, that is able to print 3D flexible electronics consisting of SUV-ICE covalently bonded with other dielectric elastomer, such as SUV-ICE strain sensors, and a flexible mini-keyboard.
